(under the class definition) Process or apparatus which includes a step or means for boring a hole in the earth, combined with a step or means located within the hole relating to subjecting the earth to a force to initiate a seismic wave in the earth.
(1) Note. For classification in this subclass, the process or means causing the force must be specifically described as for generating a seismic shock and not left to inference.
